VEHICLE-AXLE N UT.

SPECIFICATION forming part of Letters Patent No. 658,410, datedSeptember 25, 1900.

Application filed March 12, 1900. Serial No. 8,390. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. TERRY, a citizen of the United States,residing at Pontiac, in the county of Oakland and State of Michigan,have invented certainnew and useful Improvements in Vehicle-Axle Nuts,of which the following is a specification, reference being had thereinto the accompanying drawings.

1o The invention has reference generally to axle-nuts for Vehicles, andrelates particularly to the extensible type of nut formed in twosections to permit of the nut being lengthened when desired to take upthe end play of r 5 the parts.

The principal object of my invention is to produce an axle-nut of thetype referred to that may be adjusted or extended for the purposes setforth while upon the spindle end,

zo whereby the exact adjustment required may be made, being rapidlyeffected in a minimum space of time.

A further object of the invention is to provide means for locking theextensible mem- 2 5 ber to and at any point upon its'complementarymember, whereby its exact adjustment when effected may be maintained andthe end play of the parts be completely taken up; and a still furtherobject of the invention is to 3o construct the axle-nut in such mannerthat it will be simple in construction and capable of being readilyapplied to any vehicle.

With these objects in view my invention consists in a novel constructionof the axlenut and in the peculiar formation, arrangement, andcombination of the various parts thereof, as will be more fullyhereinafter described and shown.

In the drawings, Figure l is a vertical lon- 4o gitudinal sectionthrough an axle-box and spindle and the extensible nut, showing theformation of the latter. Fig. 2 is a view in elevation of the nut asapplied to a vehicle, showing means for adjusting the same. Fig.

3 is a cross-section taken on line 0c, Fig. l; and Eig. 4 is aperspective view of the parts of the vehicle-nut detached.

The reference-letter A designates a spindle of usual constructionterminating at its free 5o end in the usual threaded nipple B, and C isthe axle-box Within which the spindle turns.

D designates a washer arranged intermediate the box and spindle-shoulderE, and E is a similar Washer bearing against the outer end G of theaxle-box. A

In construction the axle-nut is formed in two sections or members H andI, the latter or inner member being recessed to form a socket, such asJ, and intern ally screw-threaded, as at K, to permit of its engagementwith 6o the nipple B. This member has a polygonal surface L formed uponits exterior, as plainly shown in Fig. 4, and one corner thereof isbeveled, as at M, for the purpose hereinafter set forth. The outer orwhat I term the extensible member H of the nut has a polygonal opening Oformed therein, conforming in configuration to the surface L, and ispreferably provided with a wrench-hold P upon its exterior and with anannular flange Q, 7o which serves as a dust-guard and also as abearing-surface against which an adjusting device, such as the wrench R,(shown in Fig. 2,) may bear. The member H is also provided with a'depending annular flange S, which 75 bears in the usual manner againstthe washer G, as shown in Fig. 1.

T represents the locking device, which in this particular case is in theform of a Wedge, as plainly shown in Fig. 4, the latter being 8otriangular in form. One surface of the Wedge is adapted to bear againstthe bevel portion M of the member'L and engage between said surface anda corresponding corner of the polygonal opening O, as plainlyillustrated Vin Fig. s.

In assembling the parts the extensible member is placed upon the spindleend and the inner member I of the nut is threaded upon the nipple B,said member extending within 9c the extensible member, as shown. Theparts are then locked by means of the wedge. To effect the adjustment,the nut members having a sliding engagement one'with another, as shown,the operator drives the extensible member inwardly the desired amount,which movement is not in any Way retardedby the wedge, and after theadjustment is effected the wedge is driven and locks the vmemberstogether.

The advantages of this construction of nut will be readily apparent whenit is taken into A lOO consideration that the nut as an entirety isalways upon the spindle end, and the necessity of removing the same fromthe threaded nipple for the purpose of making temporary adjustment. isdispensed with; also, t'or this reason a perfect adj ustment. can bemade in minimum space of time, as when the extensible m'ember is driveninwardly as far as possible the end play of the parts is taken up andthe adjustmentis at once made. By einploying the locking devicedescribed itis possible to lock the extensible member at any point thatmay be desired alongy its complementary member, so that after theadjustment has been effected the extensible member is locked in itsadjusted position.

I have shown the extensible member of the nut as provided with aWrench-hold to permit of the nut beine; turned. This, however, is not anessential construction, as the turning could be effected, if desired, byapplying the wrenchto the end of the inner member. I therefore do notdesire to limit myself to the exact formation, as it is possible forvarious modifications to be made'and different forms ot' nut membersused without in any manner departing from the spirit of my invention.

WVliat l claim as my invention is- An extensi ble axle-nut com prisingtwo telescoping members or sections, the inner member being recessed andthreaded internally and havint.lr a polygonal outer surface, and anouter or extensible member having an opening formedtherein conforming inconfiguration to said polygonal surface and provided upon its exteriorwith a wrench-hold, and alockingwedge extendingr lengthwise of the nutand between the members, substantially as described.

In testimony whereof I aiiix my signature in presence of two Witnesses.

GEORGE W'. TERRY.
